The test apparatus comprises an electrolysis chamber fixed on a reaction frame operating platform, and further comprises a multi-group stress applying device for loading tension and compression stress to multiple surfaces of a concrete test piece. The apparatus and the method can test the influences of electric accelerated corrosion on the performances of hydraulic concrete under the action of the long-term constant bidirectional tension and compression force, and solve a problem that the electric accelerated corrosion condition of the hydraulic concrete cannot studied under the action of the continuous bidirectional tension and compression force in the prior art.

Description

technical field [0001] The invention relates to an electrically accelerated concrete corrosion test device and method for simulating two-way tension and pressure action, and belongs to the technical field of simulation tests. Background technique [0002] Hydraulic concrete structures such as high-gravity dams, arch dams, and face dams have been subjected to water pressure, temperature stress, and wave impact for a long time, and are generally in a three-dimensional stress state, with some areas under compression and some under tension. The structural stress state is complex and the stress level is different; for example, the high concrete face rockfill dam, the middle face of the valley is generally under compression, and the two sides of the valley are generally under tension. The same face is subjected to temperature stress at different elevations due to the change of reservoir water temperature with the elevation , so that part of the structure is under tension and part ...
